Controversy remains on how to treat lower pole calculi between 1 and 2 cm of size. Treatment options like shock wave lithotripsy (SWL) or percutaneous stone treatment (PCNL) are associated with poor stone-free rates or high morbidity.Due to the ongoing development in endourologic technology, especially in flexible renoscopy, laser technique and grasping(More)
PURPOSE Renal cell carcinomas (RCC) frequently express the gastrin-releasing peptide receptor (GRP-R). Gastrin-releasing peptide (GRP) stimulates tumor cell proliferation and neoangiogenesis. Tumor-associated macrophages (TAM) comprise an important cellular component of these tumors. We analyzed the GRP/GRP-R network in clear cell RCC (ccRCC) and non-clear(More)
In the framework of metric-free electrodynamics, we start with a linear spacetime relation between the excitation 2-form H = (D, H) and the field strength 2-form F = (E, B). This linear relation is constraint by the so-called closure relation. We solve this system algebraically and extend a previous analysis such as to include also singular solutions. Using(More)
The purpose of this study was to obtain authoritative opinion on the importance of joint noises. Experts in the areas of orthopedics, rheumatology, and arthritis were asked four questions to evaluate the importance of clicking and crepitus in joints other than the temporomandibular joint (TMJ). The general response of these experts indicated that clicking(More)
INTRODUCTION We report the early postoperative results of the first prospective, randomized comparison of two commercially available thulium lasers with different wavelengths for the treatment of benign prostatic obstruction (BPO). MATERIALS AND METHODS From January to June 2013, 80 consecutive patients were randomized for Thulium VapoEnucleation of the(More)
The natural course of untreated asymptomatic caliceal calculi has not been clearly defined, especially in terms of disease progression, and the indications for and outcomes of surgical intervention are not precise. Caliceal stones may remain asymptomatic but, in case of migration, ureteral calculi can cause acute ureteric colic with severe complications.(More)
